go ... I ... I was told the crowd causing an increase in precipitation over one I'm helping covered and welcome to this new sub extra I'm joining me from the law Street Journal in London is Capgemini at that time thank you so much for joining me and I understand this new study is going to be in the journal Science ... tell us about it that very interesting here at the study on class ... well it turns out that if airplanes fly to certain types of clouds ... they have a cooling effect behind them and ... that cooling effect and Steve and ... convince ... the water vapor into ice crystals Quinten ... which then appeared to fall as snow or rain ... and what what about the the the the science behind it the the chemistry behind that that was actually happening within the class ... looking into cloud water is usually sits in a Super Cool stay so it's still a quit stay up to minus forty degrees Celsius ... when airplanes fly its to this class ... the and behind trains between North behind its competitive instincts and expanding and according to basic physics ... coolness I mean you have that additional cooling it turns the ... well water drops into ice that my stand to situation affects gets bigger and bigger and bigger ... times editor ... and eventually if the conditions are right ... in the snow ... the lesson is something we know the cause of cloud seeding ... sorry preserves think that I think that similar to what we know its cloud seeding ... yes ... when you see clouds his BCP introduced some kind of chemical ... into a cloud what ... does it is a chemical component of a second ups and ... the water drops and can dance around Rob ... Walker paper condenses round ups and downs it into snow ... or rain drops to stand for PBS ... and this is the Fullman reached ... the ... airplane be ... has a cooling effect despite the physics of the remake thing over the reasons behind the tennis ... is causing additional cooling ... ducts has an effect on the structure of the clouds in such a way that it did snow ... day at the weekend is it that way you can ... in essence control the weather now from your article you that you point out that the Beijing weather modification Office famously its cloud seeding had that if out menial impact to make sure that it didn't rain during the games that perhaps before ... Vince Bradley experiments to seed clouds of the Chinese example is one of them is the hundred percent clear whether ... it actually worked or when it was ... just good luck that have recently been picks in two thousand ate up Tuqiri and prevent ... have been other examples ... and scientists will tell you that the extent to which ... cloud seeding works is often overstate it that ... they believe they need looks ten to fifteen percent target ... so is this that he got them I know that they're calling for perhaps some changes in how we determine what the weather will be whether they'll be more rain or snow around airports were these clouds are way fifth aircraft to fly through them up perhaps added chains in how planes RTI so what could possibly be the outcome of this study in terms of the season with some of the practical consequences if you have love of planes ... leaving and arriving at airports through cloud company expects the love of this cooling effect and the grandparents to mount super stations ... and there have been a couple of examples scientists have found ... with the success ... of more research has begun though before ... we have ... in a robust evidence linking ... you know aircraft to the intense precipitation around in ... but ... rather than for how every one example scientists wasn't playing ... and that this was in two thousandseven ... lineup Colorado ATMs ... they don't just that that ground radar state-run found at the end ... of the weather in and around get the money was lent out that this recession and so no such ... it affects the instruments become nothing in the people some of the late Ron this all ... but a lot of snow had fallen ... to commercial aircraft turboprop planes had just flown up to the cloud ... forty five minutes early ... and apparently ... that's what triggered snowfall so the couple both actually samples to buttress this idea ... however things look more robust research needs to be done before we can conclusively say ... that major airports to get more snow ... when mainstay often at ... RINO and to think that captain I thank you so much for joining me ... Ivan figure it out tonight to Wall Street Journal in
